COATING EYELETS.

SPECIFICATION forming part of Letters Patent No. 764,454, dated July 5,1904.

Application filed March 10 1904. Serial No. 197.408. (No model.)

To all whom it may concern:

Be it known that I, ISAAC W. GILES, a citizen of the United States, anda resident of New Bedford, in the county of Bristol and State ofMassachusetts, have made certain new and useful Improvements in CoatingEyelets, of

which the following is a specification.

Eyelets, especially such as are applied to shoes and garments, arecoated with Japan or other kind of varnish or paint. In applying thecoat, which is commonly done by means of rotating rolls, thefunnel-shaped throats or passages of the eyelets are apt to becomefilled more or less, and thus obstructed by an accumulation of thecoating material therein. I have found that this may be removed from theeyelets and more evenly distributed on the enlarged ends or heads of thesame by means of an air blast or current directed through the eyelets.

In the accompanying drawings I illustrate the method and apparatus bywhich my invention is carried out.

Figure 1 is a perspective view including the main portions of theapparatus, and Fig. 2 is a detail section illustrating the attachment ofthe eyelets to a holder or paper-board.

The eyelets w are attached to a paper-board 1 by inserting them in holestherein that is to say, the eyelets, which are tapered in the usual way,are forced into holes in the board, which are made of slightly lessdiameter than the greatest diameter of the body of the eyelets. Theeyelets are thus held by friction while the coat is applied thereto. Thepaper boards or strips 1, holding a series of eyelets w, as shown, aresuccessively carried forward between rolls 5 and 6, the latter beingprovided with circumferential grooves correspending in number andlocation to the longitudinal rows of the eyelets in the board 1. Thusthe upper ends of the eyelets do not come in contact with the r0116,while their lower ends or heads pass in contact with the roll 5. Thelatter takes up varnish or other fluent coating material from thetransfer-roll 4:, which in turn receives it from the take-up roll 3,that rotates in a vat 2, containing a suitable quantity of the coatingmaterial. Thus the heads of the eyelets a: are coated, and in thisoperation their throats or passages are obstructed more or less by asurplus quantity of the coating material. This is removed or distributedby means of the apparatus composed of an air-chamber 7, a pipe 8, and ablower or exhaust-fan 9. The chamber 7 is made of the same or a greaterwidth than the eyelet-carrying board or strip 1 and is also providedwith a mouth or opening 7*, the same being located on the upper side ofthe chamber and extending nearly the width of the strip 1. a

It is apparent that if a suction be created by the fan 9 air will bedrawn down through the eyelets and into the chamber 7, as indi cated byarrows, and, on the other hand, if the air-current be forced upwardthrough the chamber 7 a series of blasts or currents will be directedupward through the eyelets, with the same eifect'as in the other case.Thus while either suction or a forced blast may be employed I prefer theformer as being more effective and as securing a better distribution ofthe Japan varnish or other material with which the eyelets may becoated.

A particular advantage of my method and apparatus is that a much thickercoat may be applied to the eyelets at one operation than has beenheretofore practicable, and the coat is also applied in sufficientquantity to extend to the outer or peripheral edge of the bend or flangeof the eyelets.

It is apparent that the mouth 7 of the airchamber must be placed asclose as practicable to the board 1, and it should also be arrangedquite near the rolls 5 and 6----in fact, as near as possible.

What I claim is r 1. In coating eyelets, the improved method of removingand distributing the surplus varnish or other fluent coating materialwhich accumulates in the throats thereof, by producing a suction belowthe eyelets, whereby a series of induced downward currents of air areproduced, as described.

2. The combination, with means for applyingacoating material and astripcarrying eyelets in the manner described, of an air-blast attachmentcomprising an air-chamber having a mouth over Whichthe eyelets arepassed. and means for producinga blast, substantially as described.

3. The combination, With an eyelet-carrying strip and rolls for applyinga coatingmaterial to the eyelets, of an air-suction chamber arrangedcontiguous to the rolls andhav- I0 ing an open mouth on the upper side,and an exhaust-fan connected with said chamber, whereby downwardcurrents of air through the eyelets may be produced as described.
